Err, the third paragraph and beyond are all about rules.
DEVFS(8) FreeBSD System Manager's Manual DEVFS(8)
NAME
devfs -- DEVFS control
SYNOPSIS
devfs [-m mount-point] keyword argument ...
DESCRIPTION
The devfs utility provides an interface to manipulate properties of
devfs(5) mounts.
The keyword argument determines the context for the rest of the argu-
ments. For example, most of the commands related to the rule subsystem
must be preceded by the rule keyword. The following flags are common to
all keywords:
-m mount-point
Operate on mount-point, which is expected to be a
devfs(5) mount. If this option is not specified, devfs
operates on /dev.
Rule Subsystem
The devfs(5) rule subsystem provides a way for the administrator of a
system to control the attributes of DEVFS nodes. Each DEVFS mount-point
has a ``ruleset'', or a list of rules, associated with it. When a device
driver creates a new node, all the rules in the ruleset associated with
each mount-point are applied (see below) before the node becomes visible
to the userland. This permits the administrator to change the proper-
ties, including the visibility, of certain nodes. For example, one might
want to hide all disk nodes in a jail(2)'s /dev.
As far as having these actions done automatically on boot, look at
the /etc/defaults/devfs.rules file. You can make a custom one in /etc.
